Felipe trained as a biomedical engineer in his native Colombia before obtaining a PhD from the Biomedical Engineering department of Duke University. At Duke, working in the laboratory of Ashutosh Chilkoti, he focused on the engineering of genetically-encoded, self-assembling protein polymers. An important outcome of this PhD work was the elucidation of sequence rules to program the phase separation behavior of intrinsically disordered proteins (IDPs). Motivated by a newly acquired ability to engineer the phase behavior of IDPs, for his postdoctoral work he turned to their poorly-understood biology. To pursue skin as an outstanding biological system, Felipe joined the group of Elaine Fuchs at Rockefeller University. Felipe’s postdoctoral research led to the discovery that liquid-liquid phase separation drives the process of skin barrier formation. In 2020, he established the Quiroz Lab in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, where he is currently an Assistant Professor. Felipe is the recipient of multiple research awards, including a Career Award at the Scientific Interface from the Burroughs Wellcome Fund and the NIH Director’s New Innovator Award.
My primary interest is floating ice systems - Jupiter's moon Europa and Earth's ice shelves. I am interested in how these environments work and how they may become habitable. I have chosen to focus on Europa because of its potential to have what other places may not have: a stable source of energy from tides that can power geological cycles over the lifetime of the solar system. At its most basic form, life is like a battery, depending upon redox reactions to move electrons. A planetary proxy for this is activity, whereby a planet recycles through geologic processes, and maintains chemical gradients of which life can take advantage. Without recycling, it is possible that even once habitable environments can become inhospitable. This is where terrestrial process analogs come into the picture - by studying how ice and water interact in environments on Earth we can better understand the surface indications of such on Europa (and other icy worlds). My work provides a framework by which to remotely understand planetary cryospheres and test hypotheses, until such time as subsurface characterization becomes possible by radar sounding, landed seismology, or one day, roving submersibles. Much work remains to correlate observations and models of terrestrial icy environments - excellent process analogs for the icy satellites - with planetary observations. I think about how to incorporate melting, hydrofracture, hydraulic flow, and now brine infiltration as process analogs into constructing models for the formation of Europa's geologic terrain and to study the implications for ice shell recycling and ice-ocean interactions. The inclusion of realistic analogs in our backyard-Earth's poles -using imaging and geophysical techniques is a common thread of this work, giving tangible ways to generate and test hypotheses relevant to environments on Earth and Europa. In the long term, I envision constructing systems-science level models of the Europan environment to understand its habitability and enable future exploration. I'm lucky to work with a talented group of students, post docs, and collaborators who share this vision and continue to make my life's passion, understanding the worlds around us, tenable.

I am an environmental microbiologist interested in the dynamics of microbial systems. My research is motivated by the beliefs that microbes are a frontier for natural history and scientific discovery, and that exploring this frontier is necessary and important for understanding biological diversity and its changing role in ecosystem processes. The first major research theme in my lab explores how aquatic microbes respond to environmental change, notably declines in ocean oxygen content. The second major theme explores how life in symbiosis drives microbial evolution and ecology. My research targets diverse systems, from the marine water column to the intestinal microbiomes of fishes. This research aims to identify metabolic properties that underlie the ecology of microbes and microbe-host systems, the evolutionary context under which these functions arose, and the role of these functions in ecosystem-scale processes in a changing environment.
I am an Associate Professor in the Department of Microbiology and Immunology at Montana State University and an Adjunct Professor in the School of Biological Sciences at Georgia Tech. I received a B.A. in Biology from Middlebury College and a Ph.D. in Organismic and Evolutionary Biology from Harvard University. I worked as a Postdoctoral Fellow at MIT for two years before moving to Georgia Tech in January 2011. In February 2020, I moved my lab to the mountains of Montana. My work has been recognized through an NSF CAREER award, a Sloan Research Fellowship, and a Simons Foundation Early Career investigator award.
Ryanodine receptors (RyRs) are intracellular ion channels that mediate the release of calcium from intracellular stores. RyR1 and RyR2 are the predominate isoforms in skeletal and cardiac muscle, respectively where they play a central role in excitation-contraction coupling. RyRs are the largest known ion channels and are regulated by a multitude of endogenous effectors including ions, small molecules, and accessory proteins. An area of interest is the regulation of these channels by endogenous effectors, especially as it relates to altered contractile function associated with cardiac ischemia, skeletal muscle fatigue and aging.
Because of their central role in cellular calcium regulation, defects in RyR channels can lead to potentially fatal disorders. Mutations in RyR1 give rise to the pharmacogenetic skeletal muscle disorder, malignant hyperthermia (MH). RyR2 mutations have been identified in catecholaminergic polymorphic ventricular tachycardia. We are interested in determining the molecular mechanisms by which these mutations alter RyR channel function.
We analyze channel function on multiples levels of organization. Sarcoplasmic reticulum vesicle [3H]ryanodine binding is used to examine large populations of channels. We incorporate channels into artificial lipid bilayers in order to record single channel currents and assess channel kinetics. Calcium release from permeabilized muscle fibers provides a method of examining RyR function in situ. My research has two long-range goals. The first is to understand how intracellular calcium is regulated and how alterations in the regulation effects cell function. The second goal is to understand the RyR regulatory sites that might be exploited for the development of pharmacological compounds to treat disorders of cellular calcium regulation.
We study the simple larval nervous system of our closest invertebrate relatives, the tunicates. Tunicates, like us, belong to the Chordate phylum, but have very simple embryos and compact genomes. The laboratory model tunicate Ciona has only 177 neurons and is the only chordate with a fully mapped "connectome". We take advantage of this simplicity to understand molecular mechanisms that may underlie human neurodevelopment. We use transcriptome profiling to assay global transcriptional dynamics in neural progenitors during Ciona development, and use CRISPR/Cas9 to knock out important transcription factors and their downstream targets to understand how these gene networks control neuronal specification, morphology, physiology, neurotransmitter identity, and connectivity.
